"The person I love most in this world is myself." This is Luo Yang's life creed, but his creed was shaken when he discovered that he had inappropriate thoughts about his roommate, Ai Xian. Ai Xian was like a ray of light that illuminated Luo Yang's life. Before that, Luo Yang's life had no dreams or wishes, only reality and endless depression. Although he knew how to enjoy hardship, he still hated this kind of life. He is an extremely self-centered person, but he also hates himself. He is a contradictory subject. Ai Xian is a person with ideals and pursuits. Although he lives in this society, he is like the people in the Peach Blossom Land. He has his own dreams. Although they are small, they make Luo Yang envious to death. He slowly guides Luo Yang's thoughts and slowly discovers Luo Yang's concerns. Luo Yang later discovered that they were actually the same in nature. They were both unsatisfied with the status quo, had the same dream, and had a common language. Luo Yang regards Ai Xian as his confidant, but his relationship is slowly deteriorating. What should he do?
